The Senators centre has set a timetable of six weeks to return from his latest shoulder injury.

While it’s the same shoulder that required off-season surgery, Regin is hoping that six weeks of rehabbing will do the trick for now.

Regin didn’t consider the possibility of having another surgery in the last couple of weeks, but he hasn’t ruled out the possibility that he’ll have to go under the knife again following the 2011-12 season.

“I’m pretty happy that it’s only rehab and I can get back to playing,” said Regin, who hurt his left shoulder for a second time this season in a collision on Oct. 20 with the Jets’ Nik Antropov. “With problems with the same shoulder I thought I might have to go back (for surgery), but the results showed that it wasn’t necessary.

“I’m happy that I can do my rehab and, hopefully, get back soon.”

Regin said it hasn’t been easy sitting on the sidelines.

“It’s tough. I’ve barely missed games in my career, so this is the first time I’ve (done) it and I guess you learn from that, too,” said Regin. “It’s tough to be out, but there’s not much you can do about it, just try to stay positive and focus on the things you can do.”

Regin said he considered all his options.

“I talked to different doctors just to make sure and everybody I spoke to said (surgery) wouldn’t help me much right now,” said Regin. “I’m going to give it a couple more weeks to make sure I’m strong enough when I get back. It sounds long, but it’s not that bad, it’s six weeks from now and hopefully I can play the rest of the games after that.”

AULD’s well again

G Alex Auld skated Wednesday and will likely be ready to back up Craig Anderson on Friday against the Habs. That means G Robin Lehner will be sent back to Binghamton to play in the AHL this weekend.
